  • Twine tail collector system for agricultural balers
    Patent number: 4805391
    Abstract: A system for collecting twine tails on an agricultural baler includes a suction fan connected by hoses to mouth devices which partially envelop the knotters on the baler. Another hose connects the suction fan to a container. During operation, the suction fan acts to convey twine tails from the knotters into the container where they are collected. The container has an open mesh lid allowing egress of dust and small particles of debris but preventing egress of the twine tails and large particles of debris.
